目的 探讨新生儿缺氧缺血性脑病SPECT显像的特点。方法 对 30例符合新生儿缺氧缺血性脑病诊断和分度标准的患儿和 10例正常新生儿进行SPECT脑血流灌注断层显像 ,并与CT、MRI进行比较。结果 2 2例同时做SPECT、CT和MRI的患儿中 ,轻度组 7例 ,SPECT、CT和MRI阳性数分别为 7例、3例和 5例 ;中度组 10例中 ,3种方法的阳性数分别为 10例、8例和 9例 ;重度组 5例 ,3种方法均为阳性 ;SPECT、CT和MRI总的阳性检出率分别为 10 0 %、72 7%和 86 4%。结论 SPECT显像是诊断该病较灵敏的方法 ,与CT、MRI结合能对脑组织的生理、病理及代谢、功能状态作出诊断。
Objective To investigate the characteristics of SPECT imaging in neonatal hypoxic-ischemic encephalopathy. Methods Thirty patients with normal neonates with hypoxic-ischemic encephalopathy diagnosed and indexed and 10 normal neonates underwent SPECT CT perfusion imaging and compared with CT and MRI. Results Among the 22 children who underwent SPECT, CT and MRI at the same time, 7 cases were mild, 7 cases were SPECT, CT and MRI positive, 3 cases and 5 cases were positive respectively. Among the 10 cases, 3 cases The positive rates of SPECT, CT and MRI were 10%, 72% and 86%, respectively. The positive rates of SPECT, CT and MRI were 10, 8 and 9 respectively. . Conclusion SPECT imaging is a sensitive method for the diagnosis of the disease. Combined with CT and MRI, it can diagnose the physiological, pathological, metabolic and functional status of brain tissue.
